The control switch converts analog phones into VoIP phones without losing analog features. The software program runs on the user PC and acts as a “decision engine” which can access either the user’s VoIP provider or the land line. The rules for outbound calling are user-defined.

*POTS lifeline in 911 events:
One of the major concerns with VoIP technology is the processing of emergency 911 calls. Multi-Link provides a solution with the TeleVoIP Stick™ by bridging the proven PSTN 911 technology while allowing the user to benefit from the cost saving VoIP technology.
The TeleVoIP Stick™ provides the user with land line access in the event of a 911 call, power outage, or service outage. The control switch defaults all calls to the POTS line during these events, ensuring the traditional access to 911 call centers.
